How to move the wpcc (WP plugin) calculator outside of WordPress?

Question

WordPress

There is a site on WordPress. An online calculator is implemented on it using the WPCC plugin. Challenge: Use this calculator on another site (landing page) without WordPress. Maybe it's possible to load this particular calculator on another site, or somehow separate it so that it works standalone, without WP?
PS Can you recommend any standalone calculator (without reference to CMS), to which you can easily transfer the calculator from WPCC? Thank you.

Answer 1

as an option (not very good) create a page on wp only with this calculator (i.e. without a header, sidebar, footer, etc.), and then add a frame with this page to the landing page (i.e. this page will load in the right block on landos)

Answer 2

No

Answer 3

well, it's most likely possible.
you run the plugin separately, by its fatal errors you determine what exactly in wp it depends on.
well, or understand its source code and write it without wp
